Beck’s triad
combo of JVD, hypotension, and muffled heart sounds, which are s/s of pericardial tamponade
Closed chest injury
where thoracic cavity has received blunt trauma force, but chest wall integrity is intact
Commotio cordis
sudden cardiac arrest from a blow to the chest during vulnerable portion of cardiac cycle
Flail chest
when 2 or more adjacent ribs are broken in 2 or more places, where bone segments move paradoxically to ribs
hemothorax
accumulation of blood in the pleural space
myocardial contusion
bruise to the heart muscle from blunt trauma
Open chest injury
blunt or penetrating trauma to the thoracic cavity that has breached the chest wall
Open pneumothorax
where opening in the chest wall allows air to move into pleural space during inspiration, aka, sucking chest wound
Paradoxical movement
a segment of the chest wall that moves oppositely of the chest wall during inspiration and expiration
Pericardial tamponade
where blood collects within the pericardium, compressing the heart and reducing output
Pulmonary contusion
injury to lung tissue where blood leaks from damaged capillaries into interstitial spaces of the respiratory membrane, decreasing gas exchange
Simple pneumothorax
accumulation of air within pleural space
Subcutaneous emphysema
air that is trapped in the skin, resulting in tiny bubbles that can be seen, creates crepitus feeling
Sucking chest wound
aka, open pneumothorax
Tracheal deviation
